Qld police plea for dash-cam witnesses

Motorists with dashboard cameras are being urged to help police solve the suspected murder of Logan schoolgirl Tiahleigh Palmer.

Police have continued to appeal for public assistance, especially from motorists with dash-cams who travelled along Chambers Flat Road and Muchow Road, near Marsden High School on the morning of October 30.

State Emergency Service volunteers searched the area around Marsden High on Wednesday morning as the hunt for answers into how the 12-year-old girl died continues.

The search didn't provide any new information, with Tiahleigh's backpack and school uniform still missing.

Tiahleigh went missing sometime after being dropped off at the school on October 30.

Her body was found six days later on the banks of the Pimpama River on the northern end of the Gold Coast.

Motorists with dash-cams who travelled along Kerkin Road North in Pimpama, near where Tiahleigh's body was found, at any time between October 30 and November 5 are also being asked to contact police.
